Usage of this side and at my end

[Anupumh]

I would like to know how and where to use this side or at my end?

Is it right to say, this is James this side.
The problem is at your end.

[Mister Micawber]

This is James this side.-- I have no idea what this means.
The problem is at your end.- This sounds reasonable: the meaning I guess is 'the problem is your fault'.

Hi Anupumh,

My explanation would be: This is James here ..The problem seems to be with you.
